Here's an excerpt from my upcoming review in The American Conservative raising some quibbles about this fine biopic about William Wilberforce, who persuaded Parliament to ban the slave trade 200 years ago:
Unfortunately, complex historical stories like this are better suited to the leisurely pace of the television mini-series because a two-hour film has to leave out much. For instance, "Amazing Grace" fails to mention that Wilberforce was a Tory or that his religious enthusiasm was quite unfashionable during the deistic Enlightenment.
Moreover, banning the slave trade in 1807 made the abolition of slavery in the British Empire in the 1830s relatively painless. The West Indian sugar planters had routinely worked their slaves to death and thus needed fresh slaves from Africa to prosper. In contrast, slaves multiplied on the less harsh tobacco and cotton plantations of America, so our slave owners still thrived after Congress outlawed the trade in 1808.
Contemporary audiences so lack historical knowledge that veteran director Michael Apted ("Coal Miner's Daughter") and writer Steven Knight decided that there's no point in even trying to make clear who is whom in the film. For the first hour, for example, no effort is made to explain who Wilberforce's best friend "Billie" is, or why in the world Billie thinks (correctly) that he can become Prime Minister at age 24. He's just some guy named Billie who is Prime Minister for two decades. Explaining that Billie's father, William Pitt the Elder, had been the dynamic Prime Minister during the Seven Years War would only annoy the public, so why bother?
